WINDOW CONSTRUCTION.

Application filed October 23, 1925. Serial No. 64,303..:

This invention relates to windows and doors in whicha window sash is slidable vertically into and out of a suitable window well and in guideways fastened to the sidemembers of a frame.

f The principal object of the invention is the production of an inexpensive and simple form of guideway for receiving the window.

sash which guideway may be easily installed and which shall be so constructed as to be adapted to slightly vary its position when pressure is applied thereagainst or released therefrom whereby its frictional engagement with the window sash may be increased or decreased when necessity arises. This arrangement permits the loosening of the guideway when the window sticks therein, that is, when the window is too firmly gripped thereby and also permits the guideway to more firmly grip-the window sash in the event that the window sash is too loosely held thereby and rattles. i

A further object of the invention is the production of a guideway for the sash which is secured to; the side members of the frame and which is so constructed as to permit the sash to be removed therefrom without dis turbance of the securing means.

Other and further objects of the invention will appear from the subjoined description taken in connection with the accompanying drawings in which: n

Fig. 1 is a front, elevation of a Window or door frame showing our invention applied thereto.

Fig. 2 is a vertical section on the line 2 .2

gether. Said side members 1 are also preferably fastened together by a horizontal lockboard 3 which, if so desired, may have mounted thereon any suitable mechanism for raising and lowering thewindowsash 4, such mechanism however not being shown as it forms no part of our invention. The side members 1 at their lower halvespreferably have secured thereto at their inner. and outer sides a covering of upholstery or other ma: terial respectively forming the inner and outer. walls of a Window well into and out of which the sash 4 is vertically, slidable. The

sashl may be a. frameless or framed pane of glass as desired. We also preferto provide a metall c window. sill 7 which may be Secured in any manner to a flange 8 of thelockboard 3 and the inner. curved-free edge, of

which grips the upholstery or covering 5,

all as clearly shown in Fig. 2.3 The sides of said sill 7 also taper inwardly towards the center of the outside of the frame as illustrated in Fig. 3.

,9 indicates the corrugated base of springlike metallic guideways which are secured to the inner sides, as by screws 10 carrying suitable washers, to the inner sides of the bases ofthe L-shaped side members I. Said guideways are bent inwardly into the'configuration shown whereby channels 11 are formed therein frictionally and slidably receiving the side edges of the window sash. The free ends of 7 said guideways are preferably bent inwardly into parallelism with the window sash 4;. As is manifest when the screws 10 are tightened the corrugations in the base of the guideways are flattened which forces the channels 11 of said guideways inwardly towards the legsof the L-shapedmembers, thereby loosening the frictional engagement of said channels with the window sash. Conversely when thescrews 10 are loosened the channels will move towards each other and thus more firmly grip the side edges of the window sash.

For. shielding or hiding from view the upper portions of the guideways above the window well we have provided metallic garnish strips .detachably fastened to each of the side members 1. These garnish strips enhancethe ornamental appearance of the window frame and they are so bent or formed as to follow generallyin cross-section the configuration of wright-angled triangle the hypotenuse orinclined side of which is indicated at 12 while the legs thereof are indicated at 13 and 14 respectively. The'legs 1 1 preferably do not meet the legs 13 and they'are detachably secured to the inner sides of the legs of the L-shaped member 1 by suitable screws 15 access to which may be had by suitable openings .16 with which the inclined sides 12 are provided. Said inclined sides 12 follow generally the contour of the sides away from each other to release them from engagement with the sash and permit its removal.

hat. we claim as our invention is 1'. The combination with a window-casing and a Window-closure slidably mounted therein; of an L-shaped sheet-metal guidestrip secured to the said casing and having one of its arms arranged substantially perpendicular to the plane of the said window closure and formed with a longitudinal guide-groove receiving the edge thereof, and its complementary arm being longitudinally corrugated; and means for distorting the said corrugated arm to alter the angular relation between the arms of the guide-strip; whereby edge-pressure against the said window-closure may be varied.

2. The combination with a window-casing and a window-closure slidably mounted therein; of an L-shaped sheet-metal guidestrip secured to the said casing and having one of its arms arranged substantially perpendicular to the plane'of the said windowclosure and formed with a longitudinal V- shaped guide-groove receiving the edge thereof, and its complementary arm being longitudinally corrugated; and means for distortingthesaid corrugated arm to alter the angular relation between the arms of the guidestrip; whereby edge-pressiire against the said window-closure may be varied and whereby the latter is laterally stabilized by the walls of the said V-shaped groove.

Signed at New York, in the county of New York and State of New York this 22nd day o't October, A. D. 1925.
